The BSE Sensex crossed 100,000 for the first time in history on Tuesday morning, rising 487 points to touch 100,124 before settling at 100,089 by the close of trading. The milestone caps a remarkable 15-month rally driven by foreign institutional investment, strong domestic corporate earnings, and India's resilient macroeconomic fundamentals.
What Drove the Rally
Foreign institutional investors have poured approximately ₹1.8 lakh crore into Indian equities since January 2025, attracted by India's GDP growth outpacing all major economies. Corporate earnings growth has averaged 18 percent year-on-year across Nifty 50 companies, well above the long-term trend.
Key sectors driving the rally include banking, technology, and capital goods. Private banks led the charge, with HDFC Bank and ICICI Bank both hitting all-time highs. The Adani Group's infrastructure stocks and Reliance Industries contributed significantly to the index's upward march.
Perspective
- Sensex took 38 years to go from inception to 50,000 (1986-2024)
- The journey from 50,000 to 100,000 took just over two years
- India is now the world's fourth-largest equity market by capitalization
"While the headline number is psychologically significant, investors should focus on valuations, which are stretched in some pockets. Disciplined asset allocation remains essential," cautioned Nilesh Shah, MD of Kotak Mutual Fund.
Retail investor participation continues to grow, with over 15 crore demat accounts now active in India. Analysts are divided on whether the market can sustain current valuations, with price-to-earnings ratios at multi-year highs.
